How to Grow Polygonatum for High Yield and High Profit? A Detailed Guide to the Methods
SummarySite selection and land preparation: Choose clay soil or sandy soil. Planting methods: tuber transplanting and direct seed sowing. Reasonable density: poor plots can be planted at a spacing of 20cm between rows and 10cm between plants, while fertile plots can be planted at a spacing of 30cm between rows and 20cm between plants. Scientific fertilization: during the peak growth season of Polygonatum, mainly apply farmyard manure, supplemented by a small amount of phosphate fertilizer and cake fertilizer.
I. Site Selection and Land Preparation
1. Wild Polygonatum usually prefers sunlight and fertilizer, so when planting, you can choose a plot with relatively complete soil structure, sufficient fertility and a good drainage system, which can be clay soil or sandy soil.
2. Although wild Polygonatum likes light, when planting artificially, you should also choose a semi-sunny area, or build shading structures yourself.
3. When preparing the land, first spread a layer of base fertilizer evenly on top, then deep plow, then level the land, and finally dig drainage ditches around it, as well as a small ditch about every 1.5 meters in the field, and wait for sowing.
II. Planting Methods
1. Generally, sowing is carried out around August each year, or around March, and the planting methods include tuber transplanting and direct seed sowing.
2. Tuber transplanting is done around March: dig out part of the tubers from underground, divide them into small sections, dry them, place them evenly row by row, and then cover them with thin soil for planting; if necessary, cover them with a layer of straw or plastic film.
3. Direct seed sowing is even simpler: you can directly sow the seeds at a reasonable spacing and cover them with soil, and the subsequent handling method is the same as for tuber planting.
III. Reasonable Density
1. In order for Polygonatum to grow better, when sowing, the planting density needs to be arranged reasonably; generally, about 800-1000 Polygonatum plants can be planted per square meter, and planting can be carried out according to the fertility of the soil.
2. In relatively poor soil, plant at a spacing of 20cm between rows and 10cm between plants.
3. In relatively fertile plots, plant at a spacing of 30cm between rows and 20cm between plants, so that the yield of Polygonatum will be higher.
IV. Scientific Fertilization
1. Polygonatum needs relatively more nutrients during its growth process, so when topdressing, follow the principle of frequent application of thin fertilizer; the first topdressing is about 7 days after Polygonatum is planted, mainly to promote seedling growth, and a little more nitrogen fertilizer can be applied.
2. During the peak growth season, Polygonatum needs more nutrients, so after that, fertilization is needed once every month, mainly based on farmyard manure, supplemented by a small amount of phosphate fertilizer and cake fertilizer; each fertilization can be combined with weeding, which is beneficial to the nutrient absorption of Polygonatum.
